[QUOTE="Timber338, post: 1053414, member: 33822"] You're exactly right 200 fps gain for 21 extra grains is definitely less efficient. Based on your original example of 21 grains increase for the RUM, that works out to 28% increase in powder. For the 300 RUM to be as efficient as your 300 win mag, it would have to have a muzzle velocity of 3217 fps, for an equivalent 28% increase in muzzle energy. And that's just not gonna happen... I'm with dkhunt14 on this one... the WSM cartridge is about as efficient as they come while still being able to achieve reasonable velocities with the heavy bullets. The 300 WSM makes your win mag look like a waste of powder! [/QUOTE]
